* This is the directive which will create slide bookmarks for
* {@link https://developers.arcgis.com/javascript/latest/api-reference/esri-webscene-Slide.html WebScene Slides}
* for the ArcGIS API for JavaScript.
*
* Each bookmark will include the title and screenshot of the slide, and clicking on a bookmark will
* provide the slide object to a callback function (`on-slide-change`). For example, the slide provided
* in the callback will have a viewpoint property that could be used to change the location of an associated Esri SceneView.
*
* **Note:** this directive does not rely on any out of the box Esri widgets or view models.
* It demonstrates how a custom directive can be created and made to interact with other parts of the ArcGIS API for JavaScript.
*
* ## Styling and CSS
* Use the following class names to supply styling to this directive:
* - **`slides-container`**: outer-most container (`div`)
* - **`slide`**: individual slide bookmark (`span`)
* - **`active-slide`**: conditional class which is set by `ng-class` when an individual slide is clicked
*
* For example, to arrange slides horizontally and give a highlighted effect on the selected slide, the following styles could be used:
* ```css
* .slides-container {
